Comparing genetic sequences is the most accurate way of determining evolutionary relationships. This is a quantitive measure, ( it uses numbers) we can use gene sequencing to identify how much of the genetic sequence in A is the same in organism B. The greater the similarities the more likely it is they have recently evolved from a common ancestor. The closer the ancestor, the less time has passed which means there’s been less time to develop mutations a base variation. That’s why there’s more genetic similarities between two things that are closely related.
Hope that makes sense
Answer: (A) Genetic changes can be designed to make cows yield more milk.
Explanation: Milk yield per cow has more than <u>doubled</u> in the previous 40 years and many cows now produce more than 20,000 kg of milk per lactation due to genetic changes. <u>This shows that genetic changes to make cows yield more milk has already occurred.</u>
